The parts used by BMW are often generic parts which are also available from the original manufacturer at a lower cost. There are also a number of after market companies offering alternative parts.
This is intended to be a list of the alternatives. If you see additional alternative parts let us know and we can add them to the list here. At the moment the list is far from complete.
